Allow different install methods for rabbit/erlang

Currently Debian Bullseye doesn't have erlang provided by external repos
So in order to update rabbitmq version used we need to implement
rabbitmq_erlang_install_method, so that we could use external rabbitmq
with distro provided erlang.

Hpefully that is temporary solution and erlang packages for bullseye
will be built one day.
